Out of curiosity I found the Federal Reserve's official definition of inflation which is "A general, sustained upward movement of prices for goods and services in an economy." https://www.stlouisfed.org/education/glossary#sr_glossary%20index=I&sr_q=inflation&sr_e=0&sr_o=,Relevance https://www.stlouisfed.org/education/glossary#sr_glossary%20... This is interesting when applied to the early pandemic because you could argue that price increases were not general and in many cases they were not sustained either (e.g. sharp spikes in eggs and lumber were just as sharply reversed). In recent times it seems like we are seeing "true" inflation though.
